You are given an integer sequence $A$ of length $N$. Find the maximum absolute difference of two elements (with different indices) in $A$.

- $2 \leq N \leq 100$
- $1 \leq A_i \leq 10^9$
- All values in input are integers.

Input is given from Standard Input in the following format:

$N$ $A_1$ $A_2$ $...$ $A_N$

Print the maximum absolute difference of two elements (with different indices) in $A$.
